Unless you have reason to believe that the signer is taking steps to ensure 
that the sender information is accurate. I'd say that a DKIM signature from 
a reputable service provider would quite likely increase the *chance* that 
the sender information is accurate. Of course, you can't be certain (with 
any technology), because any account might be compromised by phishing.
